FM broadcasts are transmitted at high frequen-
cies and do not bend to follow the earth's surface.
Because of this, FM broadcasts generally begin
to fade at short distances from the station. Also,
FM signals are easily affected by buildings, moun-
tains, or other obstructions. These can result in
certain listening conditions which might lead you
to believe a problem exists with your radio. The
following conditions are normal and do not indi-
cate radio trouble:
AM broadcasts can be received at greater dis-
tances than FM broadcasts. This is because AM
radio waves are transmitted at low frequencies.
These long, low frequency radio waves can
follow the curvature of the earth rather than
travelling straight out into the ionosphere. In
addition, they curve around obstructions so that
they can provide better signal coverage.

How Car Audio Works
AM and FM radio signals are broadcast from
transmitter towers located around your city. They
are intercepted by the radio antenna on your car.
This signal is then received by the radio and sent
to your car speakers.
When a strong radio signal has reached your
vehicle, the precise engineering of your audio
system ensures the best possible quality repro-
duction. However, in some cases the signal
coming to your vehicle may not be strong and
clear. This can be due to factors such as the
distance from the radio station, closeness of
other strong radio stations or the presence of
buildings, bridges or other large obstructions in
the area.
